龙川江径流年内分配及变化趋势研究
Study on Change Trend of Annual Runoff Distribution in Longchuan River
摘要
Abstract
Water resources utilization and regional eco-environment are influenced by annual stream-runoff distribution, to some extend, the change of which reflects the human activity and the climate change. In this paper, the index of unevenness, complete adjustment coefficient, runoff-concentration degree, runoff-concentration period and variation were defined and calculated according to gauge records of monthly runoff of Longchuan main hydrologic stations during 1954 ~2001. The result showed that the unevenness index and complete adjustment coefficient of Xiao Huangguayuan station and Chuxiong station were in negative trend and the changing tendency was quite-similar; compared with the fitting curves, the decreasing tendency of the unevenness index, runoff-concentration degree of Chuxiong station appeared more obvious than that of Xiao Huangguanyuan station; there was no obvious change in runoff-concentration period, which of Chuxiong station came earlier than that of Xiao Huangguayuan station.关键词
